Cashu unveils NFC card for offline Bitcoin ecash payments

  • —The card holds ecash in up to 128 slots, with each tap burning tokens via a single signature
  • —It runs on the draft NUT-CCP spec; blank NXP J3R180 cards sell for about $9 each
  • —Losing the card means losing the balance, and merchants face double-spend risk until settlement
  • —End-to-end testing remains limited; merchant applications are planned
Why it matters: Offline payments remove Lightning's need for constant connectivity, widening Bitcoin's use at the point of sale.
